WIRE-WINDING MACHINE.

SPECIFICATION forming part of Letters-Patent No. 635,039, dated October 17, 1899.

Application led March 9, 1899. Serial No. 708,299. (No model.)

T0 tZZ- 7,072,071?, t ntcty concern/ Be it known that I, GEORGE D. EMERSON, a citizen of the United States, residing at New Brunswick, Middlesex county, New Jersey, have invented certain new and useful Improvements in YVire-lVinding Machinery, of which the following is a full, clear, and exact description.

My invention relates to wire-winding machinery and my object is to improve the construction of the same. l It is particularly applicable to machines for winding wire with a covering of wire, as in piano or guitar strings and the like.

In the preferred embodiment of my invention shown in the drawings, Figure 1 is a side elevation, partly in section. Fig. 2 is an enlarged longitudinal sectional view of the chuck. Fig. 3 is an end elevation of the chuck. Fig. 4 is a detail. Fig. 5 is an enlarged view of the holder for the other end of the wire. Fig. 6 is a plan View of Fig. 5.

In the embodiment shown in the drawings, 1 represents generally the frame of the machine. l

2 is a wire to be wound. This wire is held at one end in this embodiment by a chuck 3, which clasps the wire tightly, and at the other end by a holder 4, in this embodiment in theform of a hook of novel construction, over which a loop in the wire may be placed. (See Figs. 5-and 6.) This chuck has an outer cas ing 5 and an inner seat 6, tapering at its outer end, as at 7, to guide the entering end of the wire.

Sis a Vclamping-shoe, and 9 is a screw extending through the casing and adapted to be screwed down upon the shoe, clamping between it and the seat the said wire.

10 is a tubular guide for the end of the wire, extending longitudinally beyond the chuck and carried out in the direction of the axis of rotation of the chuck and in this embodiment attached to and rotatable with the chuck, as shown. In winding piano or other musical strings, for instance, it is desirable to leave a projecting end of the wire which is wound for insertion into the holes in the tunin g-pins, and to accomplish this the wire is passed through the chuck into the tubular guide 10. When the chuck and wire are rotated, this guide prevents the end of the wireprojecting from the chuck threshing around and beco1nother suitable means.

13 is a rack, and 14 a suitable latch, to pre vent the motion of the tension-carriage in either direction, as desired.

15 is in this embodiment a toothed wheel on the guide 10, and this wheel is engaged by a toothed ldriving-wheel 16 on the driving-shaft 17. The wheel 15 may be and as shown herein is of sufficient breadth of face to allow of the motion of the tension-carriage without disengagement of said wheel from the wheel 16.

18 is a shaft carrying the holder 4, and to this shaft is fixed a toothed whcel19, engaged bya second driving-wheel 20, also on the shaft 17. The gearings between the driving-:shaft 17 and the chuck 3 and holder 4 are preferably so related that the chuck 3 and holder 4 will be rotated at the same angular speed and in the same direction. The wire therefore will not be twisted, but will be rotated therewith.

48 is an arm which is provided with a suit able opening or recess 49, through or in which the wire 2 passes and 4by which the same is prevented from being drawn laterally with respect to its axis to any substantial extent by reason of the tension upon the covering-wire 24 While the latter is being wound upon the wire 2. This arm 4S may be carried by the guide 21 and travels therewith just to oneside of the portion of the wire 2 being wound, giving, therefore, avery short leverage for the covering-wire 24 to pull the wire 2 out of line.

To automatically make the covering uniform, I have provided a guide 21 for the cov-l erin g material, which is automatically moved along said wire. This movable guide is mounted on wheels 22, running on the track d3. The guide carries the spool 24 of covering inaterial, such as the wire 25, which passes over suitable pulleys or guides 26 and 27 and then to and around the wire 2. The guide can be clamped, as at 28, to a traveling belt 29, which will nuove longitudinally of said wire 2. This belt is moved by a wheel 30 on the shaft 17, whichA preferably frictionally engages a second wheel 3l, whose axis of rotation is preferably at right angles to the wheel 30. The

IOG

shaft on which wheel 3l is mounted carries a beveled gear 32, engaging beveled gear 33, around which the belt 29 passes. The Wheel 30 is preferably fixed to the shaft 17 by the key 35 so as to be movable longitudinally on said shaft 17, but not rotatable around the same. 36 is a carrier for this Wheel, which can be xed by the screw 37 to the guide 38. As this wheel 30 is movable toward and from the axis of rotation of wheel 31, the effective radius of contact of wheel 3l will be diminished or increased and the relative angular speed of the two wheels can be varied, wheel 31 being driven faster or more slowly as the wheel 30 is moved nearer to or away from, re-

spectively, the center of axis ofv rotation of 31.

form against which the projection 39 willv strike when the Wire is rotated in the direction indicated by the arrow in said ligure, as the tension of the covering-wire 25 will tend to twist the Wire 2 in a direction opposed to this motion. As the end comes in contact with the platform 42 it will prevent the loop in the end of the Wire being twisted up more tightly or untwisted. Any number of covering-Wires may be thus applied.

43 is'a gripping device for the end of the covering-wire 25, carried bythe chuck. In the present embodiment this gripping device is a clip consisting of a piece of spring metal, providing a wedge-shaped opening 44, into which the end 45 of the wire 25 lmay be jammed, as shown in Fig. 2. The machine is then started in motion, and as the chuck 3 and holder 4 are rotated the wire 25 will be wound around the wire 2 and the guide 21 Will move along the wire with a speed depending on the position of wheel 30 with reference to wheel 31 and may thus apply a regular and uniform covering to said wire.

The seat 6 is held in place by a bridge 46 across the end of the chuck, as shown. This bridge has preferably an opening 47, which aids in centering the wire. Since it is desirable to flare the opening into the chuck, as indicated, so that the Wire 2 may be more readily inserted, the bridge 47 is very useful and provides a means at the extreme forward end of the chuck for centering the wire 2, which otherwise would find its centering-support in the extreme rear end of the flared opening in the chuck.

It is obvious that many changes may be made in the embodiment herein disclosed without departing from the spirit of my invention.

What I claim isl. In a wire-Winding machine in combination a chuck to clamp the end of a Wire, said chuck havinga hollowed extension therefrom into which the end of said wire is adapted to project, a holder for the other end of said wire and means to rotate said chuck and holder, and means to apply a covering upon said Wire between said chuck and holder.
